Author Correction: Experimental extraction of the quantum effective action for a non-equilibrium many-body system

Correction to: Nature Physics https://doi.org/10.1038/s41567-020-0933-6, published online 15 June 2020.

In the version of this Letter originally published online, in the Methods subsection ‘Explicit expressions for correlators’, the citation of equation (9a) was incorrect; it should have been a citation of equation (8a). Also, in equation (8c), on the right-hand side the final term was given as +2O_aO_bO_c; it should have been −O_aO_bO_c. In equation (8d), the final seven terms on the right-hand side were given as −6O_aO_bO_cO_d + 2C_abO_cO_d + 2C_acO_dO_b + 2C_adO_bO_c + 2C_bcO_dO_a + 2C_bdO_aO_c + 2C_cdO_aO_b, but should have been −O_aO_bO_cO_d − C_abO_cO_d − C_acO_dO_b − C_adO_bO_c − C_bcO_dO_a − C_bdO_aO_c − C_cdO_aO_b. All versions of the Letter have been amended.
